FEEDER FOR HAY-PRESSES.

Specification of Letters Patent.

Application filed. April 28, 1909.

Patented A11 9, 1910. Serial No. 492,643.

To all whom it may concern:

Be it known that I, LEWIS B. WYGANT, a citizen of the United States, residing at Bellevue, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Feeders for Hay- Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to feeders for hay presses, and the object of the invention is to interpose in the feeding mechanism, or feeder, a yieldable connection, whereby, should the feeder meet with excessive resistance, one part thereof will be permitted to move relatively to another part thereof without breakage; to provide a feeder of this character having the feeder arm formed in two parts and the yieldable connection interposed between the two parts of said arm; and to provide such a yieldable connection which will combine a maximum of strength and efficiency with a minimum number of arts.

With these objects in view my invention. consists in certain novel features and in cer- I tain combinations and arrangements of parts hereinafter to be described, and then more;

disks 6 and are so arranged that they will particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a feeder embodying my invention; Fig. 2 is a top plan view of the same; and Fig. 3 is a detail View of the yieldable connection, showing the same as separated into its component parts.

In these drawings I have illustrated one embodiment of my invention and have shown the same as applied toa feeder of known construction comprising a feeder arm 1 pivotally supported at one end in bearings 2 carried by the frame 3 of a hay press. The arm 1 is provided at its forward end, or the end opposite the point of support on the frame, with a feeder head 4 adapted to enter the hopper of the press and move the hay into the path of the plunger. A yieldable connection of any suitable character is interposed between the feeder head 4: and the point of support on the main frame 3. In the present instance I have shown the feeder arm 1 as formed in 1 two parts and have interposed the yieldable ward portion of the arm 1 preferably com-.

prises two side members 5 which are preferably formed of metal or other resilient material which will permit the two members to have a certain amount of lateral movement relatively one to the other. The two members, 5, are spaced some distance apart and each has secured thereto near the inner end thereof, or the end removed from the end carrying the feeder head 4:, a disk 6. The end of each arm 5 is preferably inserted in a suitable recess or socket 7 formed in the outer face of the respective disk and is secured thereto by means of bolts 8. The inner face of each disk is provided with one or more inclined or cam surfaces 9, the two disks .beingso arranged that the cam or inclined surfaces of each disk will be arranged directly opposite one to the other. In the present instance I have shown four of these inclined surfaces on each disk and have shown the samearranged about the edge of the disk in the form of inwardly extending teeth.

Arranged between the two disks 6 is a third disk 10 provided on its opposite sides with inclined or cam surfaces 11, which surfaces are inclined in a direction opposite'to the inclination of the inclined surfaces of the interlock with the teeth or inclined surfaces of the outer disks 6 in such a manner that the threedisks will fit snugly together. The disk 10 is rigidly secured to the'inner portion of the arm 1, i. 6., the portion which is supported on the frame 3. In the present instance I have shown the disk 10 as provided with a bearing block 12 which is formed integral therewith and serves to support the same in the bearings 2 on the main frame 3. Thus, the disk 10 and .bearing block 12 comprise the rearward portion of the arm 1.

A rod 13 extends centrally through the outer disks '6 and the central disk 10 and coiled springs 1A are mounted on said rod with their inner ends bearing against the outer faces of the arms 5 to which the disks 6 are secured. The outer ends of the rod'13 are screw-threaded and have mounted thereon washers 1-5 and nuts 16, by means of which the springs 14: are confined on the rod and the tension of the springs is regulated.

stance a bar 17 is shown as rigidly secured v to the inner portion of the arm 1 by inserting the inner ends of'the two members comprising the bar in sockets or cut-away porpress in the usual manner.

The operation of the device will be readily understood. Briefly, it is as follows: The tension of the springs 14 is so adjusted that they will successfully resist the pressure exerted upon the forward portion of the feeder arm 1 during the normal operation of the feeder, and so that, should the feeder meet with an excessive resistance, as by coming into contact with some foreign object, the pressure exerted upon the forward portion of the arm 1 will overcome the tension of the springs 14 and the inclined surfaces of the disks 6 will ride over the-inclined surfaces of the central disk 10, thus permitting the rear portion of the arm 1 to continue its movement after the movement of the forward portion of the arm has been checked. The length of the inclined surfaces of the disks 6 and 10 are such that their opposite edges will never be moved beyond each other. Consequently, as soon as the rear portion of the feeder arm begins its return movement the parts will automatically resume their normal position and the operation of the feeder will be continued without interruption.

While I have shown and described a particular form of yieldable connection as interposed between the two parts of the feeding mechanism it will be apparent that this construction may be varied without departing from the principle of my invention, and, I therefore wish it to be understood that I do not desire to be limited to the details of .construction shown and described, for obvious modifications will occur to a person skilled in the art.
